How Much Can You Borrow on a Bank Statement HELOC With All Other Units Leased?

The Quick Read: It depends on occupancy and equity rather than on your leases: the line equals the property value times the combined-loan-to-value ceiling for your occupancy tier, minus every existing lien, capped at the program’s dollar maximum, so leased units do not raise the amount, though living in one unit can lift the ceiling. Bank statements document income and nothing more.

• On an investment property, the ceiling is 70% CLTV, with lines from $25,000 to $500,000 and a 700 minimum credit score.
• On a primary residence, the ceiling reaches 90% CLTV, but only at 720 or better and only up to $500,000.
• The full credit limit counts toward CLTV, whether you draw it or not.
• Rent and signed leases are not a sizing input. They show up in the appraisal, not in the formula.
• Title must sit with you or a revocable living trust. An LLC cannot hold title on this product, and every figure is subject to lender guidelines.

Do Signed Leases Increase the Line?

No. A bank statement HELOC is sized by equity, combined leverage, occupancy and credit. Rental coverage is not part of the test. Full leases make the building look stable. They do not move the ceiling.

This is the biggest difference from a DSCR loan, where the rent against the full monthly obligation is the test. A rent roll that is 100% leased can strengthen a DSCR file. On a HELOC it mostly sits in the background.

Tenants also do not block the line. A tenanted rental can qualify. The gates are title, credit, combined leverage and property type.

Which Occupancy Tier Applies When Every Other Unit Is Leased?

The phrase “all other units leased” usually means you live in one unit. When an owner occupies one unit of a 2-4 unit property, the line is reviewed as a primary residence, and a different leverage tier applies. If you live elsewhere and every unit is rented, it is an investment property.

Confirm which one you are before you look at any number. Occupancy decides the ceiling.

The 90% figure exists only at 720 or better. A line above $500,000 is for primary residences only. It caps at 75% CLTV and requires a full appraisal. Credit for a line above $500,000 is 700 or better (720 on the longer-runway program, described below).

Lower credit tiers on a primary residence step down. A 640 profile reaches 80% CLTV up to $500,000. A 620 profile reaches 70% up to $400,000. A 600 profile reaches 60% up to $400,000.

On an investment property, a 720 score buys the same 70% as a 700 score. Extra credit does not buy extra leverage there.

The network places these lines through two wholesale programs. One is a higher-leverage program. The other is a longer-runway program with a 5-year interest-only draw and a 25-year repayment period. The higher-leverage program reaches the top CLTV tiers. On 2-4 unit properties, the longer-runway program requires at least a 640 score. Each figure applies only within its own program’s terms.

How Is the Maximum Line Calculated?

Multiply the property value by the CLTV ceiling. Subtract every existing lien. Cap the result at the program’s dollar maximum. The smaller number is your limit.

The combined ratio works like this: (existing mortgage balance + new line) ÷ property value = CLTV. The new line counts at its full limit, not at the amount you draw. A paid-off property does not mean unlimited borrowing. The ceiling and dollar cap still apply.

Run the numbers on a fourplex as a modeled example, with inputs that are assumptions and not market data. Say the owner lives in one unit, rents the other three, holds a 720 score, and carries a first mortgage at 55% of value. The 90% primary-residence ceiling leaves room equal to 35% of value, subject to the $500,000 cap. A lower value or a bigger mortgage shrinks that room fast.

Now change one fact. The owner moves out and rents all four units. The same building falls under the 70% investment ceiling. With the same first mortgage, the room drops to 15% of value. The leases did not change. The occupancy label did, and that moved the amount.

Position follows what is recorded on title. With no mortgage, or if the line pays off the old one, the line sits in first position. Otherwise it is a second lien and the first mortgage stays untouched. That is a real advantage for an investor holding an older first loan.

What Do the Bank Statements Actually Do?

They document income. They do not change the equity, credit or property rules. A bank statement program uses 12 to 24 months of personal or business statements, with an expense factor that may apply, according to HousingWire’s non-QM guide.

The process works in steps. The underwriter reviews the deposits, strips out transfers between your own accounts, then applies an expense factor to business deposits. Each program sets its own expense factor. A figure you saw somewhere is an illustration, not a rule.

Rent deposits are the common snag. If rent from the leased units lands in the account you submit, it is reviewed as deposits like any others. Keep a clean trail from lease to deposit. Deposits that cannot be explained get adjusted down or excluded.

The income only has to carry your personal debt load. This line is reviewed on documented income under the applicable program, subject to lender guidelines.

What Else Does the Lender Test?

Debt-to-income usually limits a growing landlord sooner than the CLTV cap does. The maximum is 50%. Lenders test it on the interest-only payment calculated on the maximum draw, not on the amount you plan to use. A $500,000 limit is tested as if fully drawn.

At least 75% of the line is drawn at closing. The investment line runs a 5-year interest-only draw followed by a 25-year repayment period. Pricing floats across both periods and never converts to fixed. The subsequent-draw minimum is typically $1,000 after closing.

Other checks sit in the file as well:

• Credit. The minimum is 700 on an investment property. The report is no more than 90 days old at closing, with no rescores.
• Property type. Single-family, 2-4 units, PUD, townhome and condo are eligible. Mixed-use, commercial, agricultural-zoned, manufactured, log and condotel properties are not.
• Title. The property must be held by you or an inter vivos revocable living trust. If it sits in an LLC, a vesting change or a DSCR cash-out is the route.
• Portfolio. A borrower is limited to three lines. An owner with more than 15 financed properties is not eligible.
• Location. Availability is limited to 16 full-service states, which is narrower than the 41-market DSCR footprint.

Valuation is the other gate. Lines at or below $500,000 ordinarily use automated valuation. A higher CLTV may call for a second valuation, and you can ask for a full appraisal. A full appraisal is required on every line above $500,000.

For a 2-4 unit property, appraisers commonly use Form 1025, which covers two- to four-unit properties and captures a rent schedule per unit. A one-unit property uses Form 1007 for the rent schedule. Your leases appear in the appraisal’s income analysis. That is agency contrast and form names only. Agency rules do not govern these programs.

Can the Line Shrink After Closing?

Yes. Treat undrawn capacity as not guaranteed. Under the CFPB’s HELOC booklet, lenders generally may freeze or reduce a line if the home’s value falls or the borrower’s finances worsen.

Those materials are written for consumer-purpose lines. Notice rules differ on business-purpose loans. Plan as if the undrawn balance can disappear when you need it most.

Large depository banks often decline investment property entirely. Rental HELOCs are widely described as harder to get than lines on a primary home. A broker with several wholesale HELOC lenders can match the property, equity and credit profile to the program that writes it.

Edge Cases for the Other Units

The leased status of the other units matters for classification and review. It does not change the formula.

Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.

Do not carry a figure from a different tier into this one. A primary-residence number does not describe an investment property.

When Do the Leases Matter? The DSCR Cash-Out Alternative

Leases matter on a DSCR cash-out refinance. That loan replaces your first mortgage and qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. A fully leased building is exactly the profile it is built for. Read the complete DSCR loans guide for the full program picture.

*LLC title is subject to program terms.

Across most of the network, DSCR cash-out tops out around 75% LTV on a standard rental, with about 6 months of seasoning as the common expectation. Credit floors run from 620 in parts of the network to about 660 on most programs, and 700 or better opens the strongest tiers. A 1.00 coverage ratio is where select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.

Clearing 1.00 does not mean positive cash flow. The ratio compares rent to the full monthly obligation only. Repairs, vacancy, management, utilities and capex sit outside it. Reserves vary by lender, leverage and loan size, and commonly run around 6 months.

The choice is a trade. A line keeps a low-balance first loan alone, but it caps at 70% on an investment property and tests you personally. A cash-out resets the first loan, but it can reach further and tests the rent.

What Should You Prepare Before Applying?

Gather these before the file goes in:

• 12 to 24 months of personal or business bank statements, with transfers marked.
• The current mortgage statement showing the payoff balance.
• Leases and a rent roll for every leased unit.
• Proof of how the property is titled, and a vesting change if needed.
• Proof of occupancy, so the tier is clear: which unit you live in, or that you live elsewhere.
• A list of your other financed properties and existing lines.

Key Terms Defined

Combined loan-to-value (CLTV): the first mortgage balance plus the full line limit, divided by the property value.

Bank statement income: income documented from 12 to 24 months of deposits, adjusted for transfers and expenses.

Draw period: the stretch when you can borrow from the line and pay interest only.

Rent roll: a list of each unit, its tenant, its lease term and its monthly rent.

Occupancy tier: the category (primary residence, second home or investment) that sets the leverage ceiling.

DSCR: rent divided by the full monthly obligation, used on rent-tested loans and not on this line.
